Mass is an internal characteristics of a body (or a particle). Under any circumstances it remains the same.
The value of weight, however, depends on the strength of gravitational force.
Friction is the force that helps stop objects from sliding forever and ever. soccer players use friction to push themselves forward with their feet to run and start accelerating. if they want to stop, they can put their feet on the ground roughly to slow them down immediately from the rough terrain and the surface of their shoes
The mean may be calculated by summing the values of the refractive index and dividing the sum by the number of experiments. This is:
Mean = (1.45 + 1.56 + 1.54 + 1.44 + 1.54 + 1.53)/6
Mean = 1.51
The mean absolute error is the sum of the absolute values of errors divided by the number of trials:
MAE = (|1.45-1.51|+|1.56-1.51|+|1.54-1.51|+|1.44-1.51|+|1.54-1.51|+|1.53-1.51|)/6
MAE = 0.043
The fractional error is the MAE divided by the actual value:
Fractional error = 0.043 / 1.51
Fractional error = 43/1510
The percentage error is the fractional error multiplied by 100:
Percentage error = 2.85%

Sooo sorry for the late answer, but I hope it helps
Explanation:
1. Successful variations accumulate over the generations as the organisms are exposed to population pressure. "Natural Selection acts exclusively by the preservation and accumulation of variations which are beneficial under the conditions to which each creature is exposed.
2.The age of fossils are determined by carbon dating and by radioactive calculations. Since all living things are made up of carbon, the relative age of fossils, which were once live animal or plant life, can be calculated by estimating at what time the fossil was alive. When the sun’s rays shine on the animals or plants and when this collides with nitrogen it creates Carbon 14, a radioisotope. Superposition is the action of placing one thing on or above another, especially so that they coincide.
3. The geologic time scale if the record of the major events and changes in earth. Scientists created this in order to keep with the major geographical things happening on earth. Scientists created the geologic time scale using relative dating.
4. Speciation is the method of formation of new species. Speciation is of 3 types. Type 1 Allopatric Speciation Type 2 Sympatric Speciation.
Sympatric speciation happens when members of a population develop genetic differences that prevent them from reproducing with the parent type. Allopatric speciation is the evolution of species in a population that occupy different geographical areas.
5. The discovery of fossil palm tree stumps in Alaska and the unearthing of fossil alligator remains in the Arctic Circle suggested that the high latitudes were a tropical landscape 52 million years ago.
